A multiyear effort to require toxic lead service water lines to be replaced throughout Illinois is nearing the finish line.

The Senate Executive Committee on Wednesday approved HB 3739, a measure that would set timelines for lead service line replacements and create a state grant program to aid the process. The House approved the measure last month, meaning the Senate floor could be its last stop before heading to Gov. JB Pritzker’s desk.
